Adjusting the surgical microscope
Notes on adjustment
– The distance between the objective lens and the working area depends on
the focal length of the objective lens used.
– Only a correctly adjusted working distance will provide an optimum image
at all selectable magnifications.
To permit fast setup of the microscope, it is advisable to store the pupillary
distances and prescriptions of the different users so that they can be easily
preset during system preparation.
Adjusting the
interpupillary distance
• Set the minimum magnification on the main microscope using the foot
control panel.
• Position the main microscope above the surgical field.
• Use the knob (1) to adjust the distance of the eyepieces (2) on the binocular
tube in such a way that the two eyepiece images merge into one.
